I have installed PHP 4 with Apache 1.3 and everything works just fine if the .php file is in the main root directory.
The problem occurs when I try to open .php files from my virtual hosts, then I get an errormessage in my browser, something like this:
"Failed opening file test.php for inclusion (include_path = /www/users... "
It seems like it does not find the .php file.

I have tried to add the path to my .php file in the include_path and several other paths in both php.ini and httpd.conf.
